The calculation formula of bank loan interest is: interest = principal interest rate, loan term, and the annual interest rate of bank loan is about 4.5%, so the interest of loan for 50,000 years is 50,000 times 4.5% = 2,250 yuan.

So the interest on a bank loan of 50,000 yuan a year is about 2,000 yuan, but the interest on applying for a loan in a bank is often not calculated like this. After the loan, you can apply for installment repayment, so the interest generated in each installment will be much lower.

Interest is the use fee of money in a certain period of time, and it refers to the reward that money holders (creditors) get from borrowers (debtors) for lending money or monetary capital. Including deposit interest, loan interest and interest generated by various bonds.

1. Money other than the principal of deposits and loans (different from "principal").

2. The abstract interest point refers to the value added when monetary funds are injected into the real economy and returned. In a less abstract sense, interest generally refers to the remuneration paid by the borrower (debtor) to the lender (creditor) for using the borrowed currency or capital. Also known as the symmetry of sub-fund and parent fund (principal).

The calculation formula of interest is: interest = principal × interest rate × deposit period (i.e. time).

Interest is the reward that the fund owner gets for lending the fund, which comes from a part of the profits that the producer makes by using the fund to play its operational functions. Refers to the value-added amount brought by monetary funds injected into the real economy and returned.

The calculation formula is: interest = principal × interest rate × deposit period × 100%.

3. Classification of bank interest

According to the different nature of banking business, it can be divided into bank interest receivable and bank interest payable.

Interest receivable refers to the remuneration that the bank obtains from the borrower by lending to the borrower; It is the price that the borrower must pay for using the funds; It is also part of the bank's profits.

Interest payable refers to the remuneration paid to depositors by banks to absorb their deposits; It is the price that banks must pay to absorb deposits, and it is also part of the cost of banks.

What is the maximum loan interest stipulated by the state?

The state stipulates that the maximum interest rate of private lending is four times the benchmark interest rate of banks, depending on the specific loan period. For example, if your loan is a one-year loan and the benchmark interest rate of the People's Bank of China is 6%, then the interest rate of private lending cannot exceed 24%, otherwise it will be illegal.

7% interest of 500,000 = 5,000,007% = 35,000 yuan, which is one year's interest.

The highest interest rate of personal loans mainly depends on two aspects. The first is what kind of loan the bank you choose has, and the second is the value of your collateral (pledge).

At this stage, all banks are controlling loans because the country has raised the reserve ratio. If you want to make personal consumption loans, it is estimated that few banks can do it, and even if you do, the interest rate is relatively high.

As for the value of collateral, if you are a real estate mortgage, the general procedure is to find an appraisal company to issue an appraisal report first, and then multiply your appraisal price by a certain proportion to calculate your loan amount.
